DUMPING BOAT.

SPECIFICATION forming part of Letters Patent No. 298,668, dated May 13, 1884.

I Application filed January 17, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, MIcI-IAEL S. COLEMAN, of the city, county, and State of New York, have invented a new and useful Improvement in Dumping-Boats, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my improved dumping-boat. Fig. 2 is a sectional side elevation of the same. Fig. 3 is a stern elevation of the same. Fig. 4 is a sectional plan view of a part of the stern enlarged,showing the construction for making the gates water-tight. Fig. 5 is a side elevation of the bow of the boat. Fig. 6 is a side elevation, partly in section, of the separable part of the lever. Fig.

7 is a side elevation of one of the tripline guide-standards.

The object of this invention is to facilitate the unloading of garbage-boats and other boats whose load is to be discharged into the water, and also to promote convenience in operating such boats.

The invention consists in a dumping-boat constructed with flat top and bottom, and with upper and lower air and water tight compartments in one side provided with sternopenings closed by lever-operated gates. The stern openings are surrounded by a frame provided with packing and with tapered grooves, to receive tapered gates operated by levers, so that the saidopenings can be readily opened and can be closed air and water tight. The lever of the lower compartment is provided with a separable section, to which is attached a tripline passing through the eyes of separable standards connected with the bulwark of the boat, whereby the said lever can be readily operated from the tow-boat, and the said levcr-section, eye-standards, and trip-line will be automatically detached from the boat when turned over, and saved.- To the top and bot tom of the bow of the boat are attached the ends of a draw-bar having upper and lower loops to receive the ring of the tow-line, and provided with pins for securing the said ring in the upper loop, the said pin being connected with the boat by a chain, to prevent it from being lost when it drops out and releases the tow-line ring as the boat turns over, so that the said ring can be readily raised into and secured in the upper loop, as will be hereinafter fully described.

A represents the boat, the top and bottom of which are made flat, and are surrounded by a bulwark, B, so that either can be used as a deck to receive the load.

In the forward part of the vessel, at a little distance from the bow, is an air and water tight vertical transverse partition, 0, forming an air-chamber, D.

From the partition 0 to the stern of the boat, and at or a little distance from the central line, is formed an air and water tight par tition, F, forming two compartments, one of which is divided into two compartments, G H, by an air and water tight horizontal partition, I. The partitionlmay, if desired, be extended across the chamber J to strengthen the boat, but need not beair-tightwithin the said chamher.

In the stern of the boat A, upon the opposite sides of the partition I, are formed two openings, K, leading into the chambers G H, which are closed by two gates, L, worked in grooves in a frame, M, attached to the stern of the boat around the openings K. The gates L are tapered, and the grooves in which the said gates work are tapered at the opposite sides of the openings K, so that the said gates, when pushed shut,will be forced snugly against packing N, secured to the frames M around the openings K, so that the said openings will be closed air and water tight.

To thegates L are pivoted the ends of the connecting-rods O, the other erids of which are pivoted to levers P. The levers are pivoted to the stern of the boat, and their ends extend to or nearly to the top and bottom of the said boat, and are rounded or otherwise formed to fit into a socket in the lower end of the separable part or section Q, to the upper end of which is attached the end of the tripline B. The'line It passes around a cleat, S, attached to the bulwark of the boat at or near the stern, through eyes in the upper ends of short standards T, and passes thence to the tug towing-the boat. The lower ends of the standards fit loosely in sockets in the bulwark of the boat.

U is the draw-bar, the ends of which are bolted to the top and bottom of the bow of the boat, and its middle part is vertical. In the draw-bar U, at the top and bottom of the bow of the boat, are formed upwardly and forwardly inclined loops or bends V, to receive the ring W, to which the end of the tow-line or cable X is. attached. When the loaded boat is being towed, the ring W is secured in the upper loop, V, by a pin, Y,- inserted loosely in holes in the arms of the said loop, and which is connected with the bow of the boat by a short chain, Z, to prevent it from being lost.

In using the boat the load is placed upon the deck that happens to be upward, and the loaded boat is towed to the dumping-place. The trip-line R is then operated to open the gate Lof the lower compartment, H, and allow water to flow into and fill the said compart- 'ment.

The weight of the water thus admitted tilts the boat, discharges the load, and causes the boat to turn over. This brings the waterfilled compartment upward, which allows the water to flow out of the compartment H, and the boat can be towed back to receive another load. As the boat turns over,the pin Y drops out and hangs by its chain Z, and the standard Tand lever-section Q become detached from the boat, and are drawn on board the tug by means of the'trip-li'ne B. When the boat has been drawn to the loading-place,the'ring W is drawn up the bar U by a boat-hook or other suitable means from the lower to the upper loop, V, and the pin Y is inserted in place, the door L is closed, the standards T are inserted in their sockets, the lever-section Q is applied to the endof the lever P of the lower door, L, and the boat is ready to receive another load and be again drawn to the dumpwith openings which are closed by lever-opera the separable eye-standards T and the trip-.

line B, substantially as herein shown and described, whereby the said lever can be readily operated from the tug to open the gate and dump the load, and the said lever-sections,

standards, and trip-line will be automatically detached from the boat and saved, as set forth.

3. In a dumping-boat, the combination, with the bow of the boat, of the draw-bar U, having upper andlower loops, V, and the sepa rable pin Y and its connecting-chain Z, substantially as herein shown and described, whereby the tow-line ring will be released automatically when the boat turns over, and can be readily raised into and secured in the upper loop without disconnecting the said tow-line, as set forth. 7 p

4:- The -combination, with a dumping-boat constructed with water-tight compartments having openings to admit and discharge the water for tilting orcapsizing the boat, of a frame, M, provided with a tapering groove,

and of a tapered gate, L, substantially as shown and described.

5. The combination, with a dumping-boat constructed with water-tight compartments having openings, of a frame, M, provided with packing N, a tapered gate, L, working in a correspondingly-tapered groove, and a lever, P, for operating said gate, substantially as shown and described.

6. The combination, with a dumping-boat, of a gate-operating lever, I, a separable lever-section, Q, and the trip-line R, substantially as herein shown and described.
